The COLMI R12 Smart Ring is a sleek, next-generation wearable designed to merge style and health monitoring in a compact form. With its built-in display and touch interface, it offers glanceable access to essential metrics—no need to constantly pull out your phone. Its premium features, durable construction, and wireless charging capability make it ideal for tech lovers, wellness enthusiasts, or anyone who wants unobtrusive biometric tracking.
The R12 is intended for everyday wear: tracking your heart rate, sleep, activity, and more. It supports gesture controls (for tasks like swiping through videos or controlling a smartphone camera) and multiple sport modes. Water resistance (IP68 + up to 5 ATM) gives it durability in wet conditions, so it can withstand swimming, showering, or rainy days.
It’s compatible with Android and iOS via the companion QRing app, which unlocks deeper analytics, long-term trends, and customization options.

Additional Highlights & Notes
Gesture / Remote Control: The R12 allows you to perform simple gestures (e.g. swiping motions) to interact with content, scroll video feeds, or even trigger the camera shutter—useful for hands-free control.
Display Convenience: Rather than relying solely on the companion app, you can see key stats (time, steps, heart rate, battery) directly on the ring’s display.
Durability in Water: Some listings claim 5 ATM rating (suitable for swimming) in addition to IP68 dust/water protection.
Limitations / Caveats: As with most consumer-grade wearables, biometric readings (heart rate, sleep, blood metrics) should be taken as indicative, not medical-grade.
Battery Life: Because of the display and functionality, expect that battery life may be shorter than simpler rings (in reviews, ~4–5 days is mentioned)
